Started out implementing '/proc/pid/checkpointable' which reports 0 or 1
depending on whether a process is checkpointable atm. But realized that
some patches that were discussed earlier are missing from Dave Hansen's

This patchset includes those missing patches plus two new patches that
create /proc/pid/checkpointable.

        [PATCH 1/6] Checkpoint multiple processes
        [PATCH 2/6] Restart multiple processes
        [PATCH 3/6] Check 'may_checkpoint()' early
        [PATCH 4/6] Deny external checkpoint unless task is frozen
        [PATCH 5/6] Define and use proc_pid_checkpointable()
        [PATCH 6/6] Explain reason for task being uncheckpointable
